I oughta tell you the logic behind no tape name... besides the "no messing with metadata" deal.

In AE, you can make video animation files out of items that don't have the slightest telationship to a tape, like jpegs or Illustrator and Photoshop documents. No tape. Not even a KiPro or SD card or P2 card. Just files. No single point of origin like a tape.

You can also have comps that contain video from all sorts of sources -- tapes, KiPros, SDs, P2s, doesn't matter -- which makes assigning a single tape name pretty fruitless. No single point of origin like a tape.

If you look at it that way, you may still find it frustrating but you might also see why Adobe didn't give a lot of thought to incorporating such a feature.
